IMPROVEMENT IN EJ ECTORS.

The Schedule referred `to in theseLettex-s Patent and making part of thesame.

.the peculiar manner fully described hereafter, so that it can bereadily adjusted to raise and force water; or

Ito raise a large volume of water without forcing the same; or to raisea moderate volume of water, and force itto a limited height, ascircumstances may re- Figures l and 2 in the accompanying drawingillustrate the instrument, with the movable parts in differentposit-ions.

r'eneral Description.

A is the exterior casing of the instrument, terminating at one end in abranch, a, to which the discharge-pipe can be secured, and at theopposite end in a tubular projection, b, having internal screw-threadsadapted to external threads on a nozzle, B, which projects into thecasing A, and is reduced in diameter at 2;, where it forms a valve,adapted to. aI seat on the edge of an opening in a partition, f, in thecasing A.

'I he nozzle B has any desired number of holes, It, and can he soadjusted that these holes shall-connnunicate with the suction-branch 'iof the casing A, as

shown in tig. l, or cut ott from such communication,

as shown in iig. 2.

Dis an inner nozzle, conmmnicating with a steampipe, and having ascrew-thread adapted to an internal thread in the head of the nozzle B,so that it can be adjusted until its end 'mf is in contact with the in'-terior of the nozzle B, where the latter is reduced in diameter.

As seen in tig. l, the instrument is adjusted for raising and forcingwater, the opening in the partition f being closed, so that the watermust pass from the suction-branch t throughl the openings l1, and forcedthence, by and with the steam, through the end e ot' the nozzle, andthrough thc branch a.

When the instrument is required for simply raising water without forcingit, the nozzles are adjusted to the position shown in fig'. 2, therebyclosing the openings h, exposing an annular opening, n, in the partitionj, and causing the end of the vnozzle D to be in contact with theinterior of the nozzle B, where thc latter is reduced in diameter. Thewater, in this case, must pass from the suction-branch t' directlythrough the annular'opening n in the partition f, and thence with thejet ot' steam i'om the nozzle D-througli the branch a..

A much larger volume of water can he raised and simply delivered at thedischarge-branch a' by the instrument when in thecondition shown in fig.2 than when it has been adjusted to both raise and force the water, asshown in tig. 1.

` The nozzles may he so adjusted that the openings h. are partlyexpo'seth'the end of the nozzle m a short.

distance i'om its seat in the nozzle B, and the latter so adjusted as topermit a limited opening in the partitionf, in which case acomparatively large volume of water may he forced to a limited heightthrough the branch a.

It will now be seen, without further description, that the instrumentmay be readily adjusted to raise water and force the sa-me; or soadjusted as to raise a large volume of water and simply deliver itwithout forcing; or to raise a moderate supply of water and force it toa limited height, as the duty to he performed may require.

Both nozzles are furnished with tightening-nuts, so that they can hesecured after adjustment.

Claim.

lhe exterior casing A, its branches a b e', partition f, and valve-seat,iircombination with the adjustable nozzle B, adapted to the valve-seat,and having perforations It h, and steam-nozzle I) adjustable in thenozzle B, all substantially as and for the purpose described. j

In testimony whereof, I have signed my name to 'this specifica-tion inthe presence ot' two subscribing witnesses.
